More blood results

Hi I am a 28 year old female. Please could someone interpret my results for vitamins and minerals. Current symptoms - heavy periods, feeling exhausted when waking up, puffy eyes, pale skin, undereye circles, constipation, breathlessness, muscle aches and pains, legs feeling stiff. Do I need to supplement in anything? I already supplement vitamin D 800iu. Thank you


Serum ferritin 18 (15 - 150 premenopausal women)

Serum folate 2.1 (2.5 - 19.5)

Serum vitamin B12 184 (180 - 900)

25 hydroxy vitamin D2 <6.0

25 hydroxy vitamin D3 29.4

Total OH vitamin D 29.4 (>75 adequate vitamin D)

B12 is almost bottom of range and folate is deficient. Please ask for advice on

Ferritin is very low in range. Ferritin in your range is optimal 75-100. I would supplement iron with 1,000mcg vitamin C to aid absorption and minimise constipation. Retest in 4-6 months. Take iron 4 hours away from Levothyroxine.

Vitamin D 29.4 is very low and 800iu is an inadequate dose. I would buy D3 softgel capsules and supplment 10,000iu daily for 6 weeks and then reduce to 5,000iu daily for a couple of months, then reduce to 5,000iu alternate days and retest in June. Take vitamin D 4 hours away from Levothyroxine.


Have posted question on the Pernicious Anaemia forum. GP has just called me to say I have positive Intrinsic Factor antibodies so looks like Pernicious Anaemia as well.
